Microsoft Defender for Office 365: Email and collaboration reports : Mail latency report

Originally posted by Microsoft Apr 6, 2022 Microsoft 365 Apps 0 Comments

We’re updating the chart view, list view and filter options to clarify email delivery latency and latency due to detonation of the attachments / URLs (for those items that are subject to Safe Attachments and Safe Links policies).

This message is associated with Microsoft 365 Roadmap ID 93213

When this will happen:

We will begin rolling this out in mid-April and expect to complete rollout late May.

How this will affect your organization:

The Mail latency report shows you an aggregate view of the mail delivery and detonation latency within your organization. As part of this enhancement, we’re updating the chart view, list view and filter options.

Chart view:

The existing report is represented in a stacked bar chart, with Mail delivery and Detonations on top of each other. The updated chart shows these values in a grouped bar chart with Mail delivery and Detonations values next to each other.

Note:We’ve changed the terminology from ‘Mail delivery’ latency to ‘Overall’ latency to better reflect the meaning.

View image in new tabList view:

The list view now shows a single row for all the percentiles (50th, 90th and 99th). Earlier each percentile was shown in a single row.

Filter Options:

The existing report has the following filter options ‘All email’, ‘Messages that contain attachments or URLS’ and ‘Detonated email’.

You might want to update your documentation as appropriate.

These options are enhanced to give more clarity in the new report. The new options are ‘All email’ and ‘Detonated email’. The ‘Detonated email’ has two options: ‘Inline detonation’ and ‘Asynchronous detonation’. These options help show the impact on latency due to respective configurations of Safe Attachments and Safe Links policies.

• Mail latency report
• Asynchronous detonation in Safe Attachments policy settings (see Dynamic Delivery)
• Asynchronous detonation in Safe Links settings for email messages (see disable setting in ‘Wait for URL scanning to complete before delivering the message’)
